Instructions on the operation of protective untriggered gap Ð-74 :
-
Metal-ceramic protective untriggered gap P-74 possesses four discharge gaps. The flange is the joint cathode terminal. Four lamels are four anode buttons.
-
Gaps can protect simultaneously four cable conductors with opposite directions of effecting impulse of voltage.
-
Voltage is recommended to supply with the help of flexible conductors.
-
We recommend to joint to the electrodes of the gap with the help of screws using the holes on the anode buttons and the flange.
-
On-position of protective untriggered gap Ð-74 – any position.
Cooling down – natural cooling.
